[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: a screw feeder, comprising an operating table 1, a vibrating feeder 2, a nail feeding tube 3 and a nail feeding rotor 4. The vibrating feeder 2 is fixedly mounted on the operating table 1, and the vibrating feeding table 2 conveys the screws to one end of the nail feeding tube 3 through a conveying track 21. The nail feeding rotor 4 is rotatably mounted in the nail feeding tube 3, and one end of the nail feeding rotor 4 is connected to a motor 5. The nail feeding tube 3 is provided with a screw track 31 with an opening located just above the nail feeding tube 3. A photoelectric switch 6 is provided at the end of the screw track 31. By continuously rotating the nail feeding rotor 4, the screws conveyed in the vibrating feeder 2 are continuously conveyed to a position on the operating table 1 for easy access.

[0019] In this embodiment, the width of the screw track 31 is larger than the diameter of the screw by 1-1.5 mm and smaller than the diameter of the screw nut, so that the screw can be in a state where the nut is located outside the nail feeding tube 3 and the screw rod is located inside the nail feeding tube 3.

[0020] In this embodiment, the nail feeding rotor 4 includes a rotating shaft 41 and a spiral blade 42. The spiral blade 42 is fixedly mounted on the rotating shaft 41. The pitch of the spiral blade 42 is twice the diameter of the screw. The continuous rotation of the spiral blade 42 pushes the screw rod portion of the screw, so that the screw located in each pitch continuously moves forward. The pitch of 2 times the diameter of the screw rod facilitates the correct falling of the screw into the spiral blade 42.

[0021] In this embodiment, the distance between the outer wall of the rotating shaft 41 and the wall of the nail feeding tube 3 is greater than the rod length of the screw, so as to prevent the bottom of the screw from touching the rotating shaft 41 and affecting the normal feeding of the screw.

[0022] In this embodiment, an adjustment groove 32 is provided at the end of the screw track 31. The adjustment groove 32 extends obliquely downward and the lowest point is higher than the horizontal axis of the nail feeding tube 3. A corresponding resistance pad is provided at the end of the nail feeding tube 3. As the spiral blade 42 continues to rotate, when the screw is transported to the adjustment groove 32, the screw will be rotated along the adjustment groove 32 by a certain angle and will be in contact with the resistance pad, so that the nail cap of the screw faces the operating table 1, which is convenient for the automatic screwdriver to take the screw.

[0023] In this embodiment, the motor 5 is electrically connected to the photoelectric switch, and the photoelectric switch 6 detects whether the screw falls into the adjustment slot 32. After the screw is detected, the photoelectric switch controls the motor 5 to stop working, and the nail feeding rotor 4 no longer rotates.

[0024] Working principle: When in use, first place a certain number of screws into the vibrating feeder 2, and convey the screws to the nail feeding tube 3 through the conveying track 21 with the nail cap facing upward. The screws continue to move forward with the rotation of the spiral blade 42 until the screws are conveyed to the adjustment groove 32. The screws will be rotated along the adjustment groove 32 at a certain angle and abut against the abutment pad, so that the nail cap of the screw faces the operating table 1, which is convenient for the automatic screwdriver to take the screws.

[0025] Based on the above, the utility model can separate batches of screws individually by providing a nail feeding tube and a nail feeding rotor, so that it is convenient for a handheld automatic screwdriver on the workbench to take out the screws individually; the adjustment slot provided at the end of the screw track can help the screw that originally stood vertically with the nail cap facing upward to rotate, so that the screw nut faces the side of the operating table, making it convenient for a handheld automatic screwdriver to insert into the pattern on the nail cap, and conveniently taking out the screws.

[0026] It is understood from common technical knowledge that the present invention may be implemented through other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
